The heat stove is just like the EFE, just to get the engine up to temp asap. It uses a vacuum operated temp switch on the air cleaner that opens a valve in the air cleaner to suck in hot air from around the exhaust manifold.
EFE just forces the exhaust on the left side to crossover in the intake manifold to the right side to heat the manifold up. You ll notice that middle port on the intake manifold on both sides. The hot air choke also runs off of that if your car had that option.
Im really liking those blue silicon vac hoses, ill have to check that out and see what other colors they have.
